GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 674,001, dated May 14, 1901.

Application filed August 2, 1900. Serial No. 25,623. (No model.)

To all whom it may concern:

Be it known that I, GEORGES DELIN, manufacturer, a citizen of Belgium, residing at 7 Boulevard Anspach, Brussels,in the Kingdom of Belgium, have invented a new and useful Gas-Heater; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improvement in gas-heaters in which the gas is fed to a burner along with a quantity of air after passing through a receptacle containing a quantity of petroleum residuum or similar hydrocarbon material and the gas and air are passed through chambers, in which they are caused to circulate and become intermingled, the mixture of air, gas, and vapor from the enriching-chamber then being burned in proximity to a superposed deflecting, reflecting, or accumulator plate, by all of which an intense heat is created. I attain these objects by such mechanism as is illustrated in the accompanying drawings, illustrating the preferred form of my invention, in which- Figure 1 is a central Vertical section, partly in elevation, of the burner and its adjuncts.

Fig. 2 is asection on line 1 2. Fig. 3 is a section on line 3 4. Fig. 4 is a top plan of the burner.

Similar characters refer to like parts throughout the several views.

The burner may be used in or with a stove or casing of any suitable form or may be used without a casing and supported on base 1.

A gas-inlet pipe 2, controlled by a cock 3, provides for the entrance of common burning gas. The gas passes up through pipe I) and escapes into box a through a number of openings 4. The box a may be provided with means for introducing a compound for enriching the gassuch as petroleum, tar, or other hydrocarbon compound-by attachment to pipe I) by means of a screw-thread, or the injector-pipe 0 may be removable from the box for a like purpose. The injector-pipe 0 extends upward from box a into the lower central portion of cylinder d. This cylinder (1 has a number of side openings h, which openings are surrounded by frusto-conical shield f. The enriched gas rising from tube 0 tends to suck in atmospheric air through holes h, and the air and gas then rise together inside cylinder d, becoming more or less commingled in this cylinder cl. The cylinder 61 has a cover 1', which cover has a central opening j, surrounded by a downwardlyextending rim or tube 6. A series of holes Z surround the central opeuingj, and the notches k in the edges of cover 1' also form openings for the passage of the mingled gas and air. These openings j, k, and Z are of different sizes and positions, and the air and gas moving upward in cylinder d are caused to eddy and gyrate, and thus become quite thoroughly commingled. As the cover '6 is a partial obstruction, a portion of the rising gas is turned back, thus producing further eddies and currents in the rising gases or vapors. A conical mixing and expansion chamber 7 surmounts the cylinder 01. In this chamber a little above cover c' there is a reticulated diaphragm or partition m, of wiregauze. The gaseous matter rising through the holes in cover '6 is broken up by the diaphragm, and as the chamber above diaphragm m becomes wider as it rises the gaseous matter expands while it mixes. A second reticulated diaphragm or burner 77. at the top of the conical chamber permits the mingled gases to rise, While restraining the flame from descending. The ignition and combustion take place just above diaphragm n. The enriched gas and air mixture in burning above the diaphragm n produces a flame which comes in contact with the deflector p. This deflector is a plate of refractory material-such as fire-brick, soapstone, refractory metal, or other material-adapted to retain heat without combustion. The plate p is preferably in the form of a conic frustum and is held in position by a light frame 0, which is attached to the cylinder d and extends above the burner. A screw-bolt B may extend centrally through the deflector p, and by means of nuts S the deflector 19 may be raised or lowered with reference to the burner.

The material of which this burner is constructed is generally metal, save as has been explained.

The combustion of a small quantity of gas in a burner of this kind produces intense eat.

The enriching material in chamber a can be renewed as often as found necessary.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a gas-heater, a gas-inflow pipe, an enriching-b0x into which the gas enters from said inflow-pipe, an ejector-pipe leading from said box, a chamber having side openings into Which chamber the said ejector extends, said chamber having a perforated partition at its upper end, and a deflector-plate suspended above said partition, all the specified elements combined substantially as described.

2. In a gas-heater, a gas-inflow pipe, an enriching-box into which said inflow-pipe extends, an ejector-pipe extending upward from said box, a cylindrical chamber having side openings, into which cylindrical chamber the ejector extends, a cover on said cylindrical chamber and having openings therein, a frusto-conical chamber above said cylindrical chamber, and a reticulated diaphragm at the top of said frustoconical chamber, all the specified elements combined substantially as described.

3. In a gas-heater, a gas-inflow pipe, an enriching-b0x provided with means for the introduction of enriching material, an ejector extending from said box, a chamberinto which said ejector extends, said chamber having side inlet-openings, a reticulated diaphragm forming a burner above the said chamber, means for supporting said diaphragm, and a plurality of interposed perforated partitions between the ejector and the reticulated burner, all the specified elements combined substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

GEORGES DELIN.
